Name: Warning Label (1)
Type: 86-003-1011
Code No.: 100-236-231
WARNING
Do not use the ORBIT mode in rough
sea.
Because the boat turns a 360-degree circle
around the waypoint a large wave or strong
wind can cause the boat to capsize.
For the figure eight mode, confirm that
no objection is in the general vicinity
of the waypoint.
The distance from the waypoint to the
turning point depends on boat's speed.
Set the turn rate properly.
Setting the too high rate may cause sudden
turn.
When connecting a geomagnetism
detection type heading sensor, correct
magnetic field deviation.
If an autopilot is used without the compens-
ation, unexpected course change may occur.
